SMOKING PIPE.

Application filed March 26, 19.23. Serial No. 627,556.

To all whom it may concern.' Y

Be it known that I, GEORGE WV. CoNLEY, a citizen of the United States,residing at heatOn, in the county of Du Page and State of Illinois, haveinvented a certain new and usefulA Improvement in Smoking Pipes, oflwhich the following is a'full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

This invention relates to improvements 1n smoking pipes. c

One obj ect of the invention is to provide Iasmoking pipe of simpleconstruction, so arranged that a cool, dry smoke is assured, whereincaking of the material at the bottom ofthe bowl is prevented, and theaccumulation of nicotine and moisture is trapped within the stem toprevent the same from reaching the users mouth. y

Y. Another object of ,ther invention is to provide a pipeof thecharacter indicated, wherein the stem and-bowl have associated therewitha draft ltube so arranged that suction will be created at the center ofthe bowl as well as at the entrance to the stem. .A Y

A lstill further object of the invention is rto provide a pipe `of thecharacter indicated whereintlie'stemV is provided with a lining and inwhich vboth the lining of the stem, and the draft tube are formed ofmaterial which is imperviousto moisture, preferably metal, `whereby theparts are prevented from absorbing nicotine. o A more specific object ofythe invention is to provide a smokingv pipe constructed ofseparate'parts, which may be easily and quickly disa'ssociated tofacilitate the cleaning of thel pipe, and wherein a draft tube having abaffle plate therein is provided and the draft tube is so arranged astoextend linto thebowl an appreciable distance.

Other objects and advantages of the invventionwwill more clearly appearfrom the description' and claims hereinafter followi In the; drawingforming a part of 'this specification, Fig. 1 isa vertical,flongitudinal, sectional view through a smoking pipe illustrating myimprovements in connection therewith. Figt 2 is a transverse, vertical,sectional view on an enlarged scale, corresponding substantially to theline 2-2 of Fig. 1, and Fig. 3 isa vertical, longitudinal, sectionalview similarjto Fig. 1 of the partson an enlarged scale. Y

In said drawings, A indicates the bowl of thek pipe, B they stem portionwhich is formed integral with the bowl, andl C the detachable mouthpiece. l i' The stem B is provided with a longitudinally extending bore10A communicating at one `end with the interior of the bowl A andadapted to receive the reduced portion 11 of the mouth piece C withinther other end thereof; the reduced portion 11 being adapted to lit thebore with sufficient tightness to hold they part-s normally inlassembled relation`and yet permitting the mouth piece to be forciblydetached' from the stem when desired. The bore 10 of the stem isprovided with a tightlylitting tubular lining 12 which is impervious -tomoisture, being preferably formed of metal. l

Y The mouth piece C has rigidly secured thereto a draft tube 13, vthelatter being driven into the slightly enlarged portion l14 of the bore15 of the mouthpiece C,

and extends from the reduced end Aportion of the mouth piece throughl.the bore of the stem into the bowl A. A metal collar 33 .is secured tothe` tube 13 near the outer end thereof, just inwardly of the end of thetubular vlining 12, the collar being spaced slightly from the lining. Asclearlyshown inFig. 1, the draft tube 13 is arranged axially' ofthe'bore 10 ofthe stem B and in spaced relation to the inner v a portionof the bowl and stem, showing' Wall yof the tubular lining 12, therebypro- Vviding an annular chamber 16.V Communication between the. rearendportion of the tube 13 and the bore 15 of the mouth piecevisestablished through the open endl 17 of vthe tube. The opposite end18 ofthe tube 13 is also open and establishescommunication between theinterior of the bowl and v.the frontend portion of the tube. .Tlietubeis provided with a plurality ofvperforations, preferably five, the sainebeing indicatedV by 19 to 23 inclusive. The perforations 19, 21 and 22are located at the upper side of the tube and the perforations'20 and 23are located at the lower side thereof.l As clearly shown in Figs. 1 and3, the perfor-ations 19, 20, 22 and 23 are arranged in sets, the firstset comprising the vertically alignedperfo rations 19 yand 20, thesecond set vcomprising the vertically aligned perforations 22 and 23.The perforations 19 and 20, formingvthe first set, are locatedA near theouter end 18 of the tube 13, beyond the collar 33 and communicatedirectly with the interior of the bowl A; the perforations 22 and 23forming the Second set,l areV located near the point where the tube 13enters the mouth' piece and communicate with the chamber 16; and theperforation 21 is located between the two sets of perforations and alsocommunicates with the chamber 16 Intermediate the opening 21, and theset of openings 22 and 23, the draft tube 13 is provided with atransversely arranged partition or baille wall 25, cutting offcommunication between the front and the rear ends of the tube 13 anddividing the same into two compartments or chambers.

The suction created in smoking the pipe will cause a vacuum to be formedin the chamber 16, thereby drawing the smoke into said chamber throughthe space between the collar 33 and the lining tube 12 and through thetube 13, the smoke passing into the tube thru the outer open end 13thereof and the diametrically'opposite perforations 19 and 20, andpassing from the tube 13 to the chamber 16 through the perforation 21.The battle plate 25 prevents smoke from directly entering the rear endof the tube 13. The smoke passes from the chamber 16 into the rearend ofthe tube 13 through the perforations 22 and 23 and out through the bore15 of the mouth piece. It will be evident that any nicotine or moisturecollecting in the chamber 16 and in the tube in front of the baffleplate 25 will accumulate in the bottom of the chamber by flowing downthe side walls of the chamber and draining off through the lowerperforations 2O of the tube 13.

Any saliva entering the rear end of the tube 13 through the mouth pieceC will pass out through the lower perforation 2li into the lower portionof the chamber 16. Should any nicotine or moisture pass into the rearend of the tube 13 through the perforation 23 the same will also passout through the perforation 24:.

The passage of smoke from the bowl through the' outer end of the tube,into the chamber 16 and out through the rear end of the `tube 13 willhave a cooling and drying tendency by reason of t-he provision of thefront chamber of the tube formed by the baffle plate 25, and the chamber16, in which the smoke may eddy and deposit its moisture.

It will be evident from the foregoing description that I have provided apipe of exceedingly simple construction, the parts of which may beeasily disassembled for cleaning and wherein the parts subject to directcontact with the smoke as it first passes out of the bowl, areconstructed of impervious material, preferably metal, thereby preventingabsorption of nicotine is merely illustrative andI contemplate all ichanges and modifications that come within the scope of the claimsappended hereto.
